To @ZZ whom t may concern,.-

Be it known that I, JOHN J.KENNELLY, a citizen of the United States,residing in the city, county, and State of New York, have in- 5 Ventedcertain new and useful Improvements in Devices for Sanding Tracks, ofwhich the following is a specification.

My invention relates to the class ofdevices employed on street railwaycars for applying 1o sand to the tracks, the device being under the'control of the driver; and the object is, in the main, to produce asimple, inexpensive and efficient device which will not be liable toabrasion and consequent deterioration by the sand getting into thejoints of the working parts. As each car must be supplied with four ofthese devices, it will Vbe obvious that economy and durability in theconstruction are important items.

2O The invention will be described with reference to the accompanyingdrawings, wherein- Figure l is a vertical longitudinal section of a partof a car provided with a sanding de- Vice embodying my invention; andFig. 2 is an under side View of the car. These views show the device ona comparatively small scale. Fig. 3 is a vertical section of the sandingdevice on a large scale, the plane of the 3 4; and Fig. 4 is a verticalsection of the device in the plane indicated by line-4, 4, in

Fig. 3. l

In Figs. l and 2, represents the floor of a car, m is the platform atoneend of the car, 002 is one of the axles, x3 are the Wheels and y is therail. These are, or may be, of the usual kind. Under the seat, z, of thecar, is arranged a hopper-like box, a, to contain sand, w. This box hasa removable cover, a', and its lower, contracted end projects'downthrough a delivery aperture in the bottom of the car.

In Figs. l and 2, A represents the sanding device as a whole, theconstruction of which will be best understood from an inspection ofFigs. 3 and 4. I

The shell of the device is made in two sections which are provided withaperturedlugs, c, to receive bolts for securing the sections rmlytogether. At the upper part of the section being designated byline 3, 3,in Fig.

shell is formed the sand-receiving hopper, b, provided with lugs, c',for securing the shell to the under side ofthe car-bottom at thedelivery aperture for the sand. At the lower part of the shell is formeda housing, bx, for the oscillating or rocking valvegd. This valve is inthe form of a short cylinder with journals, d', d', which find bearingsin thel sides of the housing. The valve has an inlet port, c, at oneside, for the sand, and an outlet port on the opposite side in which isscrewed a delivery pipe or tube,f, long enough to extend down to a pointnear the trackrail y.

Fixed on the squared extremity of one of the journals, d', of the valve,is a cog-segment, g, which gears with a similar segment, g', mounted torock on a stud or bolt, h, in a bracket, h', on the housing, hx. On theboss 70 of the segment g, is an arm, gx, which is loosely coupled to aspring-rod, z', about which is a coil spring, j, which abutsA at one endagainst an adjustable collar, 71X, on the springrod and at the other endVagainst an apertured bracket, b2, on the shell, through which thespring-rod plays. On the segment g', is an arm, g2, which is coupled toan operating rod, 7c (Figs. l and 2), whereby the valve is oscillated orrocked by the driver, gripman, or motorman of the car. Y

' Normally the spring j, holds the valve in the position seen in Figs. 3and 4; that is, with the inlet port e, out of register with the hopperZ), so that no sand can enter or pass through the valve. When in thisposition the delivery tube f, occupies a nearly horizontal position, asseen in Fig. 3; but when the valve is rocked by drawing on the rod k,the tube f, will be turned down to theposi- 9o tion seen in Fig. 1, soas to deliver the sand onto the crown of the rail y, and the inlet porte, will be brought to' a position to receive sand from the hopper. Whenthe parts are in the position seen in Fig. l the spring j, will becompressed and under tension, and when the pullfon the rod 7c, isrelaxed, the spring will again return the parts to the position seen inFig. 3.

The valve (l, is represented as hollow, but roo this is only to reducethe weight. It might be solid and the inlet port e, would in that caseextend through it diametrically to the outlet where the delivery tube f,is screwed in. The housing bx, is cut away or slotted at one side topermit of the play of the delivery tube. In order to agitate the sandand pre- Vent it from packing in the hopper l?, Jins, mi, may be set inthe valve d, in such a posi tion as to play to and fro in the hopperwhen the valve oscillates.

For the sake of economy in fitting up the castings and also to lessen asmuch as possible the number and extent of the wearing surfaces exposedto the abrading action of the sand, the valve is made to tit loosely inthe housing except about the outlet of the hopper b, where a chippingpiece or ledge, n, is provided, this piece being dressed to (it snuglyto the convex surface of the valve and preventthe sand from escapingfrom the hopper` b, into thehousing about the valve.

Any suitable means for enabling the driver, gripinan or motorman tooperate the two stan ding devices at one end of the car through themedium of the rods k, may be employed. As shown in Figs. l and 2, thereis arock-shaft, o, arranged under the car-platform and eX- tendingtransversely thereof. This shaft h as two arms, 0X, 0X, to which therespective rods 7c, are coupled, and another arm, o', at about aright-angle to the arms o", to which is coupled a pin, q, which projectsup through the platform and has on its upper end a head to receive thefoot of the operator. By pressing down the push-pin q, both of thestanding devices are operated.

The sand-delivery pipe or tube in this class of devices often becomeschoked with mud, dirt, ice, dsc., owing to its end being down i close tothe track, and to avoid this difculty I so mount this tube that it iselevated, as described, except at the moment it is in use. The deliverytube may be of any suitable material.

I have shown two sanding devices at the same end of the car, but this isnot essential. In some cases only one at each end of the car will beemployed. This is a matter which will be within the judgment of thecompany controlling the cars.

Having thus described my invention, I claim- 1. In a sanding device forcars, the combination with the shell, comprising the hopper b, andhousing bx, of the ported, oscillating valve d, mounted in bearings inthe housing and provided with a delivery tubef, fitted to the outletport of the valve, and attached to the latter a spring which holds thevalve in its normal, inoperative position, and mech-- anism for rotatingthe valve into its operative position, substantially as set forth.

2. In a sanding device for cars, the combination with a shell, having ahopper b, provided with a chipping piece orledge n, and a housing bx,below the hopper, of the ported valve (Z, mounted rotatively in saidhousing and fitting closely only to the ledge n, and means foroscillating or rocking said valve, substantially as set forth.

3. In a sanding device for cars, the combination with the shell made intwo sections and comprising a hopper b, and housing bX for the valve, ofthe ported valve d, rotatively mounted in the said housing, the tube f,secured to the valve at the outlet port, the pins m, in the upper faceof the valve, and mechanism for oscillating or rocking the valve,substantially as set forth.

4. In a sanding device for cars, the combination with the shell,comprising the hopper b and housing bx, of the ported valve d,rotatively mounted in said housing, the segment g, on the journal of thevalve, the segment g', mounted on the shell and gearing with the segmentg, the spring-rod connected with the arm of the segment g, the springy'on said rod, and the operating rod 7s, coupled to the arm on the segmentg', substantially as set forth.

5. A sanding device for cars comprising a hopper for the sand, anoscillating or rocking valve arranged under said hopper and havingopposite inlet and outlet ports, means for rocking said valve, and adelivery tube fixed to and moving with said valve, whereby the said tubeis held up out of the way when not delivering sand, substantially as setforth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

JOHN J. KENNELLY.
